GEORGE P. BLANCHARD, OF ATHENS, GEORGIA.

sPEc'rAcLEs'.

To all whom it may concern;

Be it known that I, GEORGE P. BLANCH- ARD, a citizen of the United States, residing at Athens, inthe county of Clarke and State of Georgia, have invented certain new and useful Improvements in Spectacles, of which the following is a specification. I

v This invention has relation to certain new and useful improvements 'in spectacles.

The object of my invent-ion is to provide a simply constructed, readily operated device, whereby spectacle lenses may be se curely fastened within their frames, without the" use of screws, in a manner permitting the lens or temple being readily replaced, without the use of tools.

\Vith the .above and other objects in view, the present invention consists in the combination and arrangement of parts as will be hereinafter more fully described and particularly pointed out in the appended claim, it being understood that changes in the specific structure shown and described may be made within the scope of the claim without departing from the spirit of the invent-ion.

In the drawings forming a portion of this specification, and. in which like numerals of reference indicate similar parts in the several views, Figure 1 shows a front elevational View of a lens holderconstructed according to my invention, Fig. 2 is a section on the line 2-2 of Fig. 1, Fig. 3 shows an enlarged detached detail of the vention is to provide a neat looking and substantial lens frame so constructed that the lens frame can be sprung apart permitting the ready removal of the lens or temples.

In the accompanying drawings, the numeral 5 designates a lens frame; the nu meral- 6 the upper, and the numeral 7 the lower pin ear. The lower pin ear 'has a flat upper and a flat lower surface and is carried upon the pin 20 arranged to work Specification of Letters Patent. Application filed November 22,1909. Serial No. 529,390.

(3. vide the lower socket,l0, while within" the upper face of this ear is located the latch socket 11 as clearly disclosed in Fig. 6. Within this lower socket is formed the circular shoulder 13 and the stop shoulder 12' as disclosed in Fig. 9 where I show anunder- Patented Dec. 26, 1910.

within the aperture 9 within the upper. ear The upper ear 6 is offset so as toprowith the aperture 17 and the extending stop ear 18, this car being arranged to work against the stop shoulder 12 within the lower socket of the upper ear.

The stop ear l8 limits the movement of the temple in one direction. 0

The pin 20 as, used in my invention is of one diameter as shown in Fig. 10. In this view the temple is shown upon the pin in section. The pin 20 is held in the head 28 of a latch to be described and is engaged through the lower ear, the temple and the upper ear in the order named, for the retention of these parts in operative relation, the temple being pivotally movable between the ears.

Carried upon the pin 20 is a latch including the head 28 secured upon the lower end of the pin and the upwardly extending portion 29 which is provided with the shield or latch 30 extending inwardly in spaced relation with the head 28 and arranged to snugly fit into the socket 11 within the upper ear 6. In Fig. 1, I disclose a front view of the latch in closed position. within the lower portion 28 of the latch.

From the foregoing description, it will be seen that I provide a lens frame with an upper and a lower ear, that the lower ear is held upon a .pin which pivotally supports the temple and that the pin is riveted to a latch, and that the latch is arranged to clasp over the upper ear to securely fasten the two ears together.

The operation of inserting a lens is very simple. The latch being swung outwardly,

the frame is spread by separating the ears 6 and 7, the temple being'retained upon the pin 20, after which the lens is properly introduced within the frame. The upper ear 6 is then forced down over the pin 20 and upon the lower ear securely retaining the temple therebetween. The latch'shield 30 is then swung inwardly and over the upper ear 6 into the socket 11, where the latch is se- The' pin 20 is riveted,

curely held in frictional engagement with the upper ear. After forcing the latch out of the socket, the lens and temple can of course be removed, and a new lens or temple re laced in an instant.

at is claimed is:

A spectacle comprising a lens frame, ears forming the terminal meeting ends of same, the upper ear being offset to form a latch socket above the same, a temple the ear of which is confined between the ears of the lens frame, a latch having a lower car, a pin carried by the latter, said in freely passing through said ears of the ens frame and ear of the temple, the latch having a free enga ing end, and an inwardly extending shielf forming a part of the engaging end of said latch and adapted to be snugly received by the latch socket adjacent to the lens frame and out of contact with the pin when the parts are properly brought together. i

In testimon whereof I aflix my signature, in presence 0 two witnesses. Y
